Description

technical field [0001] The present invention relates to a brake system, more precisely to a vacuum booster brake system. Background technique [0002] At present, cars are basically equipped with brake booster systems, especially the use of vacuum brake booster systems is very popular. Its principle is to use the pressure difference between the vacuum generated by the engine and the atmospheric pressure to force the rubber diaphragm in the brake vacuum booster to move and push the piston of the brake master cylinder to reduce the force of stepping on the brake pedal. [0003] The vacuum booster brake system in the prior art includes a vacuum pump and a brake booster. The vacuum pump provides a vacuum source for the brake booster. The vacuum pump is connected with the engine through the power input shaft, and the engine provides power for the vacuum pump. The power input shaft of the vacuum booster braking system in the prior art is always connected with the rotor coupling...
